It’s enough to make your head explode – Team Clinton’s astonishing press release about Barack Obama‘s grade- school essays.

Yep – grade school.

Countering an Obama jibe about a certain senator’s “long-held plans” to run for president, Hillary’s well-oiled opposition-research machine accessed its multi-terabyte database – accusing Obama of “rewriting history” by ignoring his own lingering interest in the White House.

The evidence?

A pair of essays he’d written – one back in 3rd grade and the other when he was even younger.

Naturally, the other candidates are having a field day: John Edwards confessed that in the 3rd grade, he’d wanted to be both a cowboy and Superman.

And Obama’s camp said it was preparing to counter any suggestion that he’d flip-flopped from his 2nd-grade dreams of becoming an astronaut.

Actually, this is all just a little bit spooky, to tell the truth.

Because it’s entirely possible that Team Clinton’s actual message was meant to be something like: “If we know what you did in kindergarten, Sen. Obama, just imagine what else we know about you. You’ll tread lightly, if you’re wise.”

And that would be ironic – given the years Hillary Clinton has spent decrying what she claims are smear campaigns directed at her.
